Subject: [PATCH 09/14] omxwmvdec: support VC-1 advanced profile

If VC-1 advanced profile stream is demuxed, codec_data has a sequence
header and a entry point header. At the beginning of playback,
this patch pushes a buffer which is the concatenation of sequence header,
entry point header and first frame data to decode the advanced profile
stream.
